我有一个术语,例如String term =“Torx”,我想只提取辅音。所以输出将是“Trx”。有什么想法吗?

使用字符串替换:
String Str = "torx";
Str = Str.replace("a","");
System.out.println(Str);
Str = Str.replace("e","");
System.out.println(Str);
Str = Str.replace("i","");
System.out.println(Str);
Str = Str.replace("o","");
System.out.println(Str);
Str = Str.replace("u","");
System.out.println(Str);

您可以执行David Martin的操作,不做任何替换所有元音,或者换句话说,将它们移动:
String term = "Torx";
//Replacing 'a's
term = term.replaceAll("a", "").replaceAll("A", "");
//Replacing 'e's
term = term.replaceAll("e", "").repalceAll("E", "");
//Replacing 'i's
term = term.replaceAll("i", "").replaceAll("I", "");
//Replacing 'o's
term = term.replaceAll("o", "").replaceAll("O", "");
//Replacing 'u's
term = term.replaceAll("u", "").replaceAll("U", "");
System.out.println(term); //Without vowels
或者您可以搜索所有字母并仅保存辅音:
String consonantTerm = "";
char[] letters = term.toCharArray();
for (char letter : letters) {
if (letter != 'a' && letter != 'A' &&
letter != 'e' && letter != 'E' &&
letter != 'i' && letter != 'I' &&
letter != 'o' && letter != 'O" &&
letter != 'u' && letter != 'u') {
consonantTerm += letter;
}
}
System.out.println(consonantTerm) //Without vowels
如果您希望新的String位于同一变量中。只需在for循环后添加
term = consonantTerm;
。

您应该将<string>.charAt(index)
方法与for循环一起使用,并简单地检查整个字符串。如果角色是辅音,只需将其连接到结果字符串上。
